Hiya, I'm in the UK, have a lupus-like condition, read about DHEA, did my research and presented it to my immunologist. Bloods he took said 0.1, with a reference range 0.5 – 12!! He took my research, did his own, and found a colleague of his in Cambridge had done a meta analysis, which completely supported taking it for lupus and those on steroids to mitigate their destructive side effects. The clincher for me was finding out from a Jonathan V Wright book that lack of under arm hair / reduced pubic hair signals lack of DHEA....I had pretty much none left at all! I've been on DHEA cream since October 2015, level is climbing slowly, and lots of things from skin to libido are better! NB: it's vital to use transdermal cream, NOT tablets. Tablets suffer from 'first pass' – ie go to your liver, which tries to get rid of the hormone and can create undesirable metabolites. Cream goes straight to the bloodstream, and "copies nature ". It's available online in the UK and the USA, in pump dispenser form, 15 mg a day. Put it on a different part of your body every day, for 25 days, then 5 days off, repeat! I saw Dr Wright in Seattle in July, he was concerned about metabolites but when tested I was fine. So it's important you get tested if you're going to do this long term. Not cheap, but I reckon health is the most important thing to spend your money on! And as a plus, btw, DHEA's known as the anti-aging hormone for very good reason!
